    摘要： A capacitor structure comprises a shallow drawn case having a first major side and a peripheral wall extending therefrom, the first major side having a first interior surface and the wall having a peripheral interior surface. A lid is sealingly coupled to the case along adjacent edges of the lid and the wall, the lid and said case forming an encasement of the capacitor structure, the lid comprising a second interior surface. A cathode material is disposed proximate the first and second interior surfaces, and an anode is positioned intermediate the cathode material and has a peripheral portion positioned proximate the adjacent edges. A protective layer on the peripheral portion protects the anode during the sealing process. A first insulative separator is positioned between the anode and the cathode material.

    摘要： An electrochemical cell of an implantable medical device is provided. The electrochemical cell comprises a conductive case and a cover welded to the case to form a hermetically-sealed housing. A cathode is disposed adjacent to a surface of the case within the hermetically-sealed housing and an anode is disposed within the hermetically-sealed housing. An immobilization system is disposed between the anode and the hermetically-sealed housing. The immobilization system is configured to minimize movement of the anode relative to the housing and is adapted to thermally insulate the anode during fabrication of the hermetically-sealed housing.

    摘要： A high voltage capacitor anode for an implantable medical device is fabricated by sintering, anodizing and heat treating a pressed tantalum powder slug. The sintering may be performed at a temperature between approximately 1500° C. and approximately 1600° C. for a time between approximately 3 minutes and approximately 35 minutes; subsequent anodization may be performed by immersing the slug in an electrolyte at a temperature between approximately 15° C. and approximately 30° C. and then applying a voltage across the slug, the voltage being between approximately 175 Volts and approximately 375 Volts; subsequent heat treating may be performed at a temperature between approximately 400° C. and approximately 460° C. for a time between approximately 50 minutes and approximately 65 minutes. Following heat treating, the anode is reformed by a second anodization.

    摘要： An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charge thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.

    摘要： Implantable medical devices (IMDs) and their various components, including flat electrolytic capacitors for same, and methods of making and using same and providing for outgassing of gases released during capacitor charge and discharge cycles are disclosed. A gas vent and liquid electrolyte barrier into the electrolyte fill tube lumen that is used to fill the interior case chamber with electrolyte and then needs to be closed to prevent leakage of electrolyte. The fill port is shaped to comprise a fill port tube having interior and exterior tube ends and a fill port ferrule intermediate the ends of the fill port tube and comprising a fill port ferrule flange extending trasversely to and away from the fill port tube. The fill port ferrule is mounted in an opening disposed in one of the case wall and the cover wall with the ferrule flange in seaing engagement therewith to locate the exterior tube end extending outwardly away from the fill port ferrule flange and the interior tube end within the interior case chamber. A microporous plug is injected into and fills the fill port lumen, the plug formed of a microporous material allowing the escape of gas released from the liquid electrolyte during capacitor charging while preventing escape of liquid or vaporized electrolyte.
